Just that really.
We have a house/ mortgage together. Been together 11 years. Had our ups and downs, always came out stronger....
No dc's yet but wanted to plan end of the year 
The issue is... his family don't like me, never have done. Time to walk away I think finally as it has gone on too long. It's too toxic and unhealthy and starting to make me ill to a point I feel I need my AD tablets again. My anxiety is at an all time high. No reason at all for them not liking me except me being too 'controlling' with him? He does whatever he wants and makes his own decisions.
DP is not strong enough to deal with what is happening here. It's making him ill also.
Last 2 years he was worked for his dad's business (small company) and since then it had gotten so much worse for me hence my decision now to walk away.... they know he is there everyday seeing both his parents (mum doesn't work). So why do they need to make the effort with me when he is seeing them everyday?
How do I walk away? 
I am at work at the moment but will respond as quickly as I can.
